java - 访问子节点的长度返回原始计数的两倍

Question

我一直在尝试通过获取 item 节点的长度来迭代子节点。但是，它显示的长度是原始长度的两倍。

这是我一直在使用的 XML 代码，

    <item>
        <title>Title 1</title>
        <link>http://www.example.com</link>
        <comments>http://www.example.com/#comments</comments>

    </item>

Java 代码:

NodeList nl = doc.getElementsByTagName("item");
int length = nl.getLength();
Log.d("check", "Item i count = " + length); //shows 10
for (int i = 0; i < length; i++) {
    Node currentNode = nl.item(i); // Get the first item
    String nodetestName = currentNode.getNodeName();
    NodeList nchild = currentNode.getChildNodes(); // Get the child nodes of first item
    int clength = nchild.getLength(); // Get the length of child nodes of first item (Shows 21 but original length is 10)

我应该做什么？

尝试忽略空格，它对我有用。

docBuilderFactory.setIgnoringElementContentWhitespace(true);
